摘要：This study aims to develop learning module based on the research of prevent the occurrence P. berghei bacterial infection and as well as to determine students' critical thinking skills against learning process by modules. This study is Research and Development with 4D design (define, design, development, and desimination). The results of the study found prevention of Plasmodium behergei infection from% inhibitors of erythrocytes at each dose. The dosage used in this study was a dose of 0.014 g / kgbb, 0.028 g / kgbb, 0.056 g / kgbb. The dose of 0.014 g / kg has an 9,24 % inhibitor, a dose of 0.028 g / kgbb has a 9.93% inhibitor, the dose of 0.056 g / kgbb has a 6.61% inhibitor. So the dose of 0.028 g / kgbb is the dose that most reduces the risk of P.berghei infection Mus musculus. In this study the critical thinking students of Semester 6 Chemistry University of Bengkulu classically are good category with a score of 63.13. This percentage is divided in some indicators, the indicator focus to the question is 67.92 value on the Critical criteria, considering the source can be trusted or not in the critically enough criteria with a value of 59.58, conclude by induction and consider the results of induction with a value of 64, 58 with critical criteria and identify assumptions of getting 63.13 values with critical criteria.
